Phylogenetic sequence # 198450
Size
Adults - wingspan of females 75mm (1)
Larvae - mature at 40 - 50mm (diagnostic) (1)
Identification
Adults - males are uniform in gound color with prominent, black PM line on both wings and feathery antennae. Females have a narrower PM line, especially on the hindwings, and other lines are present. Filamentous antennae (1)

Larvae - stick mimics; mostly grey-brown with many thin black lines. See Wagner photo (1)
Range
rarely encountered from scattered locations around central and southeastern US, possibly absent from North Carolina (1)
Habitat
usually low to mid-elevation oak and mixed hardwood forests (1)
Season
adults have a short flight period; mid-May in most locations (1)
Food
reared in captivity on red oak and also accepted hickory (1)
Life Cycle
larvae feed from June until August, enter diapause in the antepenultimate instar, and overwinter. In spring they molt and begin feeding again, pupate in early June. Females can lay over 500 eggs (1)
Remarks
males come to lights from 11:30 pm to 1 am, females also come to lights but less so (1)
See Also
can be separated from all other species in the genus by the upper surface of the wings being a uniform pale brownish gray. In addition, the angle of the t. p. line is about 5 mm. from the outer margin of the forewing; in all the other species, this distance is about 2 mm. [Randy Hardy]. (2)
